为合理评估多浅段航道设计通过能力及确定航道疏浚量,改进了对传统多浅段航道乘潮方式的计算方法,应用离散事件仿真方法对航道通航条件及影响因素建立航道设计通过能力的计算模型,并根据国内某航道的实际资料进行仿真计算.结果表明,针对多浅段航道的各浅段分别进行建模和疏浚方案设计的模拟计算,可以在保证航道通过能力的情况下仅对个别浅段进行疏浚,大大降低了航道的疏浚成本;同时,对多种疏浚方案进行比较计算,可以确定较优的疏浚深度,对航道建设规模确定有重要的理论价值和实际意义.
In order to reasonably evaluate the design passage capacity and determine the amount of dredging, the method of calculating the tide way in the traditional multi-shallow section of the channel is improved. The discrete event simulation method is used to establish the calculation of the passage capacity Model and a simulation calculation based on the actual data of a certain channel in China.The results show that the modeling and dredging simulation design for each shallow section of the multi-channel channel can be used only in the case of channel passing ability Shallow dredging, greatly reducing the cost of dredging channel; the same time, a variety of dredging programs to compare and calculate, you can determine the optimal depth of dredging, the scale of the channel construction has important theoretical and practical significance.
